Searching Keywords with Wildcards on Encrypted Data
Abstract. A hidden vector encryption scheme (HVE) is a derivation of identity-based encryption, where the public key is actually a vector over a certain alphabet. The decryption ke...

Entropic Security and the Encryption of High Entropy Messages
Russell and Wang [22] recently introduced an elegant, information-theoretic notion called entropic security of encryption: they required that the cipher text leak no predicate of ...

New constructions for provably-secure time-bound hierarchical key assignment schemes
A time-bound hierarchical key assignment scheme is a method to assign time-dependent encryption keys to a set of classes in a partially ordered hierarchy, in such a way that each ...

Smooth Projective Hashing and Password-Based Authenticated Key Exchange from Lattices
Abstract. We describe a public-key encryption scheme based on lattices — specifically, based on the hardness of the learning with error (LWE) problem — that is secure against ...

Towards a Type System for Security APIs
Security API analysis typically only considers a subset of an API’s functions, with results bounded by the number of function calls. Furthermore, attacks involving partial leakag...
